KEYCLOAK 20 clustering

Hi, I have been using keycloak 19.0.2-legacy which is a WildFly distribution to create a cluster using docker and docker compose. recently after I shutdown the keycloak for addition maintenance, I tried pulling the same image and add some additional changes to the standalone-ha.xml. After trying multiple times starting the keycloak service again, It was no success. I’m thinking of migrating the 19.0.2 legacy to the 20.0.1 Quarkus distribution and create a cluster, any idea?
